Retrieved from ” https: If a wasp detects the signal, it will lower its antennae and will search for the entrance to the fig. These wasps lay fertilized eggs in the syconium of a F. When wasps emerge from the syconium, they rush to the nearest syconia. The ants use the fig-fig wasp mutualism to find the fig wasps by detecting an odor that comes from the figs of the male trees. Mutualism occurs between fig and fig wasps, which creates a need for specific species of figs to be pollinated by specific species of wasps.

Views Read Edit View history. Spring, or undelayed, caprifigs usually occur on female trees. The wasps become contaminated with spores of the fungus as they contact plant surfaces upon emergence.

Blastophaga psenes – Wikipedia

Uses authors parameter link. Because the fungus grows on the ostiole, the fungus is transmitted to the wasps’ bodies when the wasp emerges pswnes the syconium through the ostiole.

Archived from the original on 27 April Winter, or delayed, caprifigs usually occur on male trees. Mating occurs within the syconium and laying eggs occurs in a syconium pseness than the one where mating occurred. Retrieved 11 October The number of offspring is low when the entry number of wasps in a syconium is high. The actual attractive substances come from the ostiole.

After mating, females emerge from the psene and search for a new nearby fig in which to lay their eggs. By being a cleptoparasite, P. Agaonidae Pollinator Hymenoptera Insects described in The wasps carry this disease on their wings and body.

The more wasps that pass through one ostiole, the more likely the wasp will contract F.

Males emerge first and start seeking females to mate with. Some wasps can carry a disease that is carried by F. The mother produces this hyperplastic tissue when she lays the eggs in the syconium.


A Study of Ficus carica L. Pesnes fungus affects both males and females. The enlarged opening enables the females to leave the syconium in search of a new one where to oviposit.

Then, males start enlarging the fig’s opening. The larvae become adults around the same time male fig flowers are ready to produce pollen.

This psened on cleptoparasitism needs attention from an expert in Biology. Later, the female lays its eggs in the ovaries of another fig by sticking its ovipositor in each flower’s style. Fundamental and Applied Nematology. Both osenes and taste also help actual entrance into a fig once the desired fig has been located. However, some ants do not respond to the odor of figs for different blastophag. They know that most fig wasps are located on male fig trees, so they use that relationship to prey on wasps.

This olfactory stimulus is specific for the wasps’ host fig in this case, F.
